24.3.2 IGMP Snooping VLAN
Click
Advanced Application > Multicast > IPv4 Multicast
in the navigation panel. Click the
IGMP Snooping
link and then the
IGMP Snooping VLAN
link to display the screen as shown. See
for more information on IGMP Snooping VLAN.
Fast Leave
Enter an IGMP fast leave timeout value (from 200 to 6,348,800) in miliseconds. Select
this option to have the Switch use this timeout to update the forwarding table for the port.
In fast leave mode, right after receiving an IGMP leave message from a host on a port,
the Switch itself sends out an IGMP Group-Specific Query (GSQ) message to determine
whether other hosts connected to the port should remain in the specific multicast group.
This helps speed up the leave process.
This defines how many seconds the Switch waits for an IGMP report before removing an
IGMP snooping membership entry when an IGMP leave message is received on this port
from a host.
Group Limited
Select this option to limit the number of multicast groups this port is allowed to join.
Max Group Num.
Enter the number of multicast groups this port is allowed to join. Once a port is registered
in the specified number of multicast groups, any new IGMP join report frame(s) is
dropped on this port.
Throttling
IGMP throttling controls how the Switch deals with the IGMP reports when the maximum
number of the IGMP groups a port can join is reached.
Select
Deny
to drop any new IGMP join report received on this port until an existing
multicast forwarding table entry is aged out.
Select
Replace
to replace an existing entry in the multicast forwarding table with the new
IGMP report(s) received on this port.
IGMP Filtering
Profile
Select the name of the IGMP filtering profile to use for this port. Otherwise, select
Default
to prohibit the port from joining any multicast group.
You can create IGMP filtering profiles in the
Multicast > IPv4 Multicast > IGMP
Snooping > IGMP Filtering Profile
screen.
IGMP Querier
Mode
The Switch treats an IGMP query port as being connected to an IGMP multicast router (or
server). The Switch forwards IGMP join or leave packets to an IGMP query port.
Select
Auto
to have the Switch use the port as an IGMP query port if the port receives
IGMP query packets.
Select
Fixed
to have the Switch always use the port as an IGMP query port. Select this
when you connect an IGMP multicast server to the port.
Select
Edge
to stop the Switch from using the port as an IGMP query port. The Switch will
not keep any record of an IGMP router being connected to this port. The Switch does not
forward IGMP join or leave packets to this port.
Apply
Click
Apply
to save your changes to the Switch’s run-time memory. The Switch loses
these changes if it is turned off or loses power, so use the
Save
link on the top navigation
panel to save your changes to the non-volatile memory when you are done configuring.
Cancel
Click
Cancel
to begin configuring this screen afresh.
